Benefits of technology

The patent text discusses how to use the front camera of a smartphone to capture images in the dark. This can be beneficial for situations where there is no light or not enough light to use the phone's flash. The technical effect of this patent is to improve the abilities of smartphones to capture images in dark environments.

Problems solved by technology

However, the front camera provided on the front surface normally has low precision, and is not equipped with any light or the like.
Particularly, it is difficult to see a moving image or a live view (a through-lens image captured before a still image is captured).

1. First Embodiment

External Perspective View of an Information Processing Device According to a First Embodiment

[0045]FIG. 1 is an external perspective view for explaining an example configuration of a first embodiment of an information processing device according to the present disclosure. The information processing device 11 in FIG. 1 is a smartphone or the like, for example, and includes an imaging unit 31 having a front camera for capturing an image in a direction opposite to the surface equipped with a display unit 33 formed with a touch panel, and an infrared light emitting unit (IRLED) 32 that emits infrared light in the imaging direction of the imaging unit 31 in the dark.

[0046]In FIG. 1, a user H holding the information processing device 11 is imaged by the imaging unit 31, and the image captured by the imaging unit 31 is displayed as a user H′ on the display unit 33.

[0047]To check the imaging angle of view in the dark, the information processing device 11 controls the infr...

2. Second Embodiment

External Perspective View of an Information Processing Device According to a Second Embodiment

[0082]In the example described above, every time a still image is captured, the backlight of the display unit 33 is made to emit intense light and function as a strobe light. However, a white light emitting unit formed with a white LED that is equivalent to the strobe light may also be prepared, and be made to function like the backlight of the display unit 33 described above.

[0083]FIG. 5 shows an example configuration of a second embodiment of an information processing device 11 in which a white light emitting unit formed with a white LED that is equivalent to the strobe light is also provided.

[0084]That is, FIG. 5 shows an example configuration of an information processing device 11 that includes a white light emitting unit (WLED) 71 formed with an LED that emits white light in the direction toward the surface on which the display unit 33 is provided, as well as the in...

third embodiment

3. Third Embodiment

Example Configuration of an Information Processing Device of a Third Embodiment

[0093]In an example described above, the backlight of the display unit 33 is made to emit intense light like a strobe light only at a time of imaging, so that white light is emitted, and an image can be appropriately captured. In the dark, however, noise easily appears even in a situation where white light is emitted. To counter this, an infrared light image captured with infrared light may be used as a luminance signal, and be combined with a chrominance signal that is a visible light image in which noise easily appears. In this manner, a high-quality image can be captured even in the dark.

[0094]FIG. 8 shows an example configuration of an information processing device 11 designed to be capable of capturing a high-quality image by using an infrared light image and a visible light image. It should be noted that, in the information processing device 11 shown in FIG. 8, components having t...

Abstract

The present disclosure relates to an information processing device, an information processing method, and a program that enable appropriate imaging with the front camera of a smartphone or the like in the dark.An LCD backlight that is a white light emitting unit is made to emit intense light as white light, and an infrared light emitting unit that emits infrared light for capturing a live view image is turned off. In such a situation, an imaging unit captures a visible light image. The present disclosure can be applied to imaging devices.
